APPARATUS FOR HANDLING STAIN.

Specification of Letters Patent.

Patented Sept. 20, 1921.

Application filed February 18, 1918. Serial No. 217,882.

1' all .whom it may concern:

Be it known that I, THOMAS LUND, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain Imsorovementsin Apparatus for Handling tain, ofwhich the following description, in connection with the accompanyingdrawings,

. is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to an apparatus for storing and stirring liquidcoloring matter and is herein illustrated as embodied in an apparatusfor storing and stirring stain or blacking used in the manufacture ofboots and shoes.

Stain, used in the manufacture of boots and shoes, is made in accordancewith various formulae but is all substantially alike in that itcomprises a suspension of solids such as wax, coloring matter, fillingmatter, etc. in a liquid which is usually largely water. It istherefore, necessary to stir the stain prior to using it and usuallywhile it. is being used.

The present invention relates to an apparatus for thoroughly performingthe stirring operation, for storing the stain and for protecting it fromdust and other foreign matter.

According to one feature of the invention, there is provided acylindrical casing having circular shelves for supporting the unstirredstain, a top for the casing to support the liquid while being stirred, arotatably stirrer supported vertically over the casing for stirring theliquid, and a rim around the top of the casing to retain any llquld thatma be spilled.

ther features comprise improved means for driving the stirrer and forconnect ng it with and disconnecting it from the driving means. I

These and other features of the invention, including certain details ofconstruction and combinations of parts, will be described as embodied inan illustrative apparatus and pointed out in the appended claims.

Referring to the I accompanying draw- The casing 1 is supported on apedestal 3 having a base 5. ormed in the casing is a compartment havingcircular shelves 7 adapted to hold bowls of different colored stain, thecompartment being adapted to be closed by a door 9 having a spring catch11. The top of the stand is a table 13 adapted to support a bowl 15 ofstain, a rim 17'bein provided to hold any stain which may acc1- dentallyfall upon the table.

Rising from the table or support is a standard 19 providedwith a seat119 for a small electric motor 21, the horizontal shaft of which carriesat its end a worm 23. An arm on the standard 19 overhangs the table 13,and in this portion is formed a vertical bore to receive t e stem 25 ofthe stirrer. A worm gear 27 which meshes with the worm 23 and isrotatably mounted in the standard 19 has a bore WhlCh is alined with thevertical bore referred to above; and the stem 25 passes loosely throughthese alined bores and has a knob 125 at its upper end which may begrasped when it is desired to raise the stirrer. In order to cause thestirrer to be rotated by the gear when the parts are in the full linepositions, there are formed upon the worm gear 27 a. air of widelyspaced projections, one of which is indicated at 29, and upon the stem25 two fin rs extending outwardly and downward y with the rounded ends.Upon moving the stem from the dotted line position to the full lineposition, the rounded ends will normally enter between the Widely spacedprojections without any rotary sitioning movement being necessary, but,s ould the fingers come nearly over the projections, the rounded endswill engage the projections and cause such slight rotation of the stemas is necessary to brlng the parts to a driving position. The stirringtool 33 is fast to the lower end of the stem 25. In order to preventdirt and oil on the worm and gear from dropping into the bowl of stain,said worm and gearare received in an irregularly cup-shaped casing 37which is herein shown as integral with the standard 19.

In the use of the apparatus, one or more bowls of stain, for example twobowls, one containing brown and the other black stain, are stored on theshelves 7 with the door 9 of the compartment closed. WVhen it is de-.sired to use one of the stains, the bowl containing it is taken from thecompartment, the

stem raised by means of the knob 125, the bowl placed upon the support,and the stem lowered. The bowl and the parts of the apparatus are atthat time in the positions shown in full lines in the figure. Theoperator.may then dip a brush into the stain and apply it to the boot orshoe, the stirrer continuing to agitate the stain as long as the stainis being used. '-There is thus rovided a portable apparatus for storingan stirring stain which may be moved from one location to another as maybe desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. An ap aratus for stirring stain comrising a table for supporting theliquid to be stirred a .motor carrying standard secured to the table andhaving an arm overhanging the liquid, a cup-shaped oil retain-' 'ingcasing carried by the overhanging arm, a worm gear and a driving wormrotatable prising a cylindrical casing having circular shelves forsupporting bowls of unstirred stain, a top for the casing to support theliquid while being stirred, a rotatable stirrer supported verticallyover the casing for stirring the liquid, and a rim around the top of thecasing to retain the liquid spilled.

In testimony whereof I have signed my I name to this specification.

THOMAS LUND.
